Hi,

This patchset adds DT support for the N900 panel. The patchset is based on
Tomi's work/dss-dt-2 branch [0]. I suggest to send the DT changes through
Benoits queue, since I have more N900 DT changes for 3.14. Also the patch
editing the rx51 boardcode can be dropped, since the file is removed in 3.14.
I included those two with this patchset, since they are needed to test the
other two patches.

I did not include a documentation for the DT API, since the omapdss
documentation is still missing.

I have successfully tested this on the N900.

I added N900 display DT support on top of my v2 series, including
pinmuxing. Can you check if it looks right and works?

git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux.git work/dss-dt

I just tried it and it does not work. On a first look the pinmuxing
looks fishy: 0x0d4 is muxed two times.

Hmm, so it is.

I'm not really familiar with SDI, I just muxed all the SDI pins, except
datapair3. I previously thought that there's only the data and clock
pairs for SDI, but the TRM revealed more sdi pins, so I included them.
It is well possible that these can be removed:

0x0d0 (PIN_OUTPUT | MUX_MODE1)   /* dss_data18.sdi_vsync */
0x0d2 (PIN_OUTPUT | MUX_MODE1)   /* dss_data19.sdi_hsync */
0x0d4 (PIN_OUTPUT | MUX_MODE1)   /* dss_data20.sdi_den */
0x0d6 (PIN_OUTPUT | MUX_MODE1)   /* dss_data21.sdi_stp */
